Hello,
I am getting the following error when trying to run pyMAPDL on my university's HPC system.
CRITICAL - - logger - handle_exception - Uncaught exception
Traceback (most recent call last):
File "/home/amia0004/scratch/conda/envs/fsi/lib/python3.11/site-packages/ansys/mapdl/core/launcher.py", line 570, in check_mapdl_launch

File "/home/amia0004/scratch/conda/envs/fsi/lib/python3.11/site-packages/ansys/mapdl/core/launcher.py", line 645, in _check_server_is_alive
raise MapdlDidNotStart("MAPDL failed to start the gRPC server")
ansys.mapdl.core.errors.MapdlDidNotStart: MAPDL failed to start the gRPC server
The above exception was the direct cause of the following exception:

I am not sure what is causing the error and it is making it difficult to complete my work. Any guidance would be appreciated.
